First comes love, then comes marriage—then comes a reality show on E!—then comes a baby in the baby carriage!

E! News confirms that NFL Denver Broncos star Eric Decker and country pop singer Jessie James are expecting their first child.

"Excited to share some news with y'all. We are having a baby :)," James tweeted Saturday morning.

But the first trimester hasn't been a smooth road for James, who is due in March 2014.

She tells E! News that things "have definitely been very rough with morning sickness," and that "it hasn't been quite blissful yet."

Despite it all, James says, "I'm just so happy to be pregnant and to become a new mommy, that's taking over the feeling of being sick."

She also revealed that the couple's first child "was a surprise at first, it wasn't planned. But when we did find out we both started crying and hugging each other. We're so excited and feel so blessed with having a baby. We're so excited."

The duo are said to be ecstatic over their future family but don't know exactly what color to paint the nursery just yet.

"We don't know [the baby's gender] yet, and I don't know when we'll find out," James said. "There's no preference, it's cliché, but we'd be so happy with either one."

The parents-to-be will very soon become familiar faces as their new show, Eric & Jessie: Game On, will be airing on E! in a couple of weeks.Viewers will get an inside look on the daily life of Decker and James, who were married in June.

Jessie is best known for her unique country pop sound and her song "Wanted" hit the Billboard Hot 100 in 2009, while Eric, who plays a wide receiver for the Broncos, is a well-known athlete in the NFL and had a breakout year in 2012 with 1,064 yards and 13 touchdowns.

And now, they're entering the next chapter of their lives together.

Congratulations!
